Adoption of 3G/UMTS IMS in NGN

• IP Multimedia Subsystem generally establish NGN
  requirements for conversational services
• With Release 6 becomes applicable to a range of
  access network types
• Access independence
• Whole Telecom industry benefits
• Market stimulation, decreasing costs (thanks to
  shared development deployment costs)
• One Development path, one NGN

6
_NGN Release 1 scope

• Consolidated by mid-2004
• Major service capabilities under consideration
  include
• Real time conversational services (Voice, Video
  telephony)
• Messaging (Instant Messaging, MMS), Presence
  management
• Content delivery (VOD, Video Streaming,
  TV-Channel distribution)
• Emulation for PSTN/ISDN migration towards NGN
• Network Architecture basis
• 3G/UMTS IMS sub-system for the support of
  real-time Conversational services (SIP-based
  session control)
• ADSL access
• WLAN (later decision)
• Design Approach
• Pragmatic bottom-up approach for Release 1
• Top-down (TIPHON-like) approach to ensure NGN
  goals

_NGN high level Roadmap
Towards a converged Wire line and Cellular NGN
2007
2005
2006
2008
2004
2006

• Release 1 bringing video Multimedia services
• Nomadicity/user-controlled roaming
• Based on use of Access network Attachment
  Subsystem
• Release 2 optimizing (dynamically allocated)
  resources usage
• According to user subscription profile and
  service use
• Release 3 introducing full Mobility
• Inter-network domain nomadicity/user-controlled
  roaming
• Higher bandwidth access(VDSL, Wi-max )

8
Leverage Global Standards for NGN

• There are a number of areas where commonality
  between 3G IMS adapted to fixed NGN
• SIP-based Call/session control
• Call server-Service/Application control
  interfaces (ISC, Dh, Sh)
• AAA (e.g. Diameter at Rf interface)
• Management
• Possible approaches are
• Define xDSL access Delta compared to relevant
  stable 3GPP specs
• Re-use and adapt IMS R6 specs for full TISPAN_NGN
  spec
• Contribute Deltas to 3GPP IMS future work
• Course of actions
• TISPAN_NGN to progress on its Release 1 work
• Discuss and define the xDSL requirements and
  differences compared to 3G IMS, taking 3GPP IMS
  Release 6 as the base reference
• Plan a joint Workshop with 3GPP SA and CN (on
  22-23 June)
• Define a stable TISPAN_NGN R1 reference
  architecture (by Sept. 04)

9
_NGN Summary

• A strong industry demand
• For new generation Multimedia services
• For the provision a PSTN/ISDN Emulation service
• First Release of specifications by mid-2005
• Based on existing global standards
• An architecture basis consisting of a set of
  subsystems
• Maximising Wire line and Cellular convergence,
  through adoption of 3G/UMTS IMS component for
  support of conversational services
• Access network attachment, Resource and admission
  control sub-systems preparing for next Releases
  capabilities support
• TISPAN to collaborate with 3GPP
• Workshop being scheduled on 22-23 June
• To identify areas of synergy and plan future
  collaboration
